A) 90
B) 90
C) 90
D) 90

Answer 1

To calculate Joanna's overall points, we subtract the points she lost from her initial points. After her first race, she had 178 points and then lost 43 and 45 points in her subsequent races, leaving her with 90 points.

Step-by-step explanation:

The question is asking us to calculate the overall points Joanna has earned after three races. Joanna started with 178 points. After losing 43 points in the second race and then 45 points in the third race, we need to perform the following calculations: Start with 178 points, subtract 43 points, and then subtract another 45 points.

Here is the step-by-step calculation:

1. Joanna's initial points: 178 points
2. After second race: 178 - 43 = 135 points
3. After third race: 135 - 45 = 90 points

Therefore, Joanna earned 90 points overall after the three races.
